Abstract: A quasi-solid-state battery formed from non-gas evolving in-situ curing of a quasi-solid-state electrolyte that includes a high swelling polymer made from a monomer with good compatibility with liquid electrolytes, and has a good reactivity for facile non-gas evolving in-situ polymerization. The monomer can be based on acrylate polymerization chemistry or an allyl group polymerization chemistry. Non-gas evolving initiators are used for non-gas evolving in-situ polymerization of acrylate or allyl monomer-based QSE. The resulting QSE additionally has high ionic conductivity, allowing for a high battery output, and a wide electrochemical window (stable for lithium metal anode and high-voltage cathodes). The resulting quasi solid electrolyte battery is not only easy to fabricate using conventional battery manufacturing practices, the non-gas evolving in-situ polymerization causes the QSE to be uniformly distributed within the battery, ensuring high-quality, safe battery performance and longevity.
